Description

Technical Field

[0001] The utility model relates to the technical field of projector bases, in particular to an AR early education projector base. Background Art

[0002] AR projectors use key technologies such as image recognition, reconstruction and automatic three-dimensional mapping. They use a secondary camera to identify the carrier in real time and use the powerful computing power of the host to map the preset content onto the carrier, i.e. augmented reality technology. It is a technology that integrates the virtual world and the real world through computer technology. It can project augmented reality scenes into the human field of vision through display devices, thereby enhancing human visual perception. There is rich technical support behind AR technology. AR projector technology is a very popular 3D projection technology nowadays. Compared with previous projectors, it can project 3D images, allowing people to watch a more realistic experience. Holographic projection uses a holographic projector, which uses the diffraction of light to form images. Now many individuals and families will also buy it for use.

[0003] However, it still has some disadvantages. For example, when using an AR early education projector, the projector is usually placed on a base. When the base is not high enough or the angle cannot be adjusted, the user needs to add external objects to adjust the height and angle. If not adjusted, some children receiving early education may not be able to see the projected image clearly, resulting in a significant reduction in the effect of early education. When projection is required in the classroom, the projector base is too high and cannot be placed on the podium, which is very inconvenient to use.

[0004] In order to solve the above problems, this application proposes an AR early education projector base. Utility Model Content

[0013] The utility model uses a telescopic round rod to set up. Before using the AR early education projector base, the telescopic inner rod is first installed in the telescopic round rod, so that the telescopic inner rod can be extended and retracted up and down in the telescopic round rod, and then the connecting round rod is installed on the fixed arc plate. When the fixed switch is turned left and right, the stable vertical plate can be driven to move up and down. When the telescopic round rod is installed in the limiting circular hole and the height of the projector base needs to be adjusted, the fixed switch is turned to the left to move the stable vertical plate out of the limiting groove, the telescopic inner rod is stretched upward and adjusted to a suitable height, and then the stable vertical plate is turned to the right to return to the limiting groove and fixed. The required height of the projector can be adjusted more quickly. When the projector needs to be used on a desktop, the connecting square plate is taken out of the connecting inner groove, the connecting inner groove is squared on the desktop, and the projector can be placed on the desktop for use.

[0014] The utility model provides a connecting cylinder. Before using the AR early education projector base, the connecting cylinder is first installed in the supporting cylinder and then fixed with a fixing screw.
